Grumman project list
« on: August 10, 2006, 01:22:38 pm »
Hoping to stir upr some discussions (and undigging of half-forgotten infos) I post the Grumman projects list found in the Francillon's book (Putnam-Naval Insitute) on Grumman Corporation. As it's very well explained in the opening remarks, it is complete till G-128 and after veeeeery sketchy (to say the best). Anyhow, till G-128 it is fairly complete (this means circa 1956-57). Enjoy.
Uh, there is an obviuos error: G-118 and G-119 have been switched. G-118 is really the XF12F.

As a gracious addition, this is the list of the G-98 projects (F11F) to give an idea of the Grumman nomenclature. Read the notes, there i a surprise (hydro-Tiger...)

I stir a dscussion myself (hopefully). Look at those two model numbers, G-107 and G-109. USAF interceptor and high-altitude WS, 1955-1956 timeframe... And the 109 includes the Eagles too.. Sound familiar? Other competitors in the phantom competition for the long-range interceptor?

G-109 has to be an alternative to the Douglas F6D Missileer, I'd think, from the description.
Grumman's G-118 (XF12F) is the Phantom II rival, no?

G-118, yes. G-108, probably, but a little bit early (1956?). And G-107? ??? Not to mention G-119.

   Hi Skybolt.
 
 Many thanks for the information.

   And so, Grumman did not participate in competition with Douglas Model D-6?? (XA4D-1).

 If there are in it to the book(Grumman Aircraft Since 1929)  more detailed of information on projects Model G-86 and G-92   if it is possible tell to us(3-view drawings, figures and specifications )

Uh, no and no... I'll search in the individual plane histories but I doubt it. The VTO could be related to the same competition of the Pogo.

   Hi Skybolt.
 
  I in one read, that:
 G-94----------XWF-1

  and in book Grumman Aircraft Since 1929 it is written so:
 G-94-----------Flex-deck F9F-7
 G-95-----------XWF-1
 
 If is in the book " Grumman Aircraft Since 1929 " about projects Model G-25, G-57, G-107 and G-124(figures,3-view drawings & specifications) show us if it is possible.

Nothing, again...  :(
As for the G-94, etc, probably in my list there is a switch of numbers, as there surely is one between G-118 and G-119.

Looking for a drawing of the single J75-powered Design 118A for my F8U-3 monograph, I wrote the Grumman archives asking for information about the Design 119, listed in Francillon's book as the "XF12F design studies", whereas the 118 is listed as "Mach 2-plus fighter study", thinking that the 119 might have originally been the designation for the single-engine version. (Note that the 118 was not the XF12F as I've discussed elsewhere.) It turns out that Skybolt is almost certainly correct about Francillon switching the designations. Although it looks like a design suitable only for a Saturday morning kiddy cartoon, I can assure you that it is straight from the Grumman archives. I've included the notation on the drawing - the reversed writing is "Design 119" and "Three View". Note that this might be one of several sketches like the Design 110 series that I've described elsewhere.

... (and undigging of half-forgotten infos) ...
I noticed that many people still don't realize the G-16 was Wildcat prototype in biplane configuration.
That's why the monoplane prototypes versions were designated G-18

Does anyone know the G-numbers for the F-111B and X-29A? I don't think Grumman had to use GD's Model 12 number for its F-111B...

Grumman's G-310 is given as the TFX/F-111.
The projected RF-111B reconnaissance version was the G-431.
The X-29A was the G-712.

Servus Maveric

These would be General Dynamics designations, not Grumman. Unfortunately these are not publicly known as far as I know. To me the F-111 is the GD-12, period. The GD designation system is pretty obscure to me, anyway, with two-digit numbers (GD-12, GD-14, Model 21, Model 44), three-digit numbers (Model 100, R-104, Models 201, 204, E-205, M-210, 218, Models 401 and 402) and four-digit numbers (Models 1600, 1601, 1602, 1700) — not to mention odd designations like VX-11... I hope someone will eventually shed some light on that question since GD is now defunct and a part of Lockheed.

  Hi Friends!

 I like to explore and compare different sources and  that I found, is "Grumman Aerospace Corp., Grumman Design 698, PDR No. 698-5, January 1978."---PDR No.698 aka Design(Model) 698, ""Future Naval Tactical Attack Aircraft (post) 1985" Grumman Aerospace Corporation, Report PDR-516-1, Vol.2, June 1971"---PDR-516---aka Design(Model) 516, Grumman Design 378B, Grumman Aircraft Engineering Corporation, ASR 378B, December 1965---ASR 378B aka Design(Model) 378B and etc.

And so, PDR and ASR---aka Design (Model), and so you can find in various sources project designation.

and more:

 Design 279---Apollo proposal.
 Design 636---NASA/HiMAT proposal.

I have one conflicting number: the UF-2 version for Norway was G-244, not G-251.
G-251 was an ASW version of Canada's CSR-110 (G-231), which also entered service with USCG as SHU-16B.

G-231    CSR-110 Albatross SAR version for Canada, also used as ASW aircraft for USCG
G-235    Gadfly tilt-wing VTOL aircraft project for U.S. Army (2- or 4-engined)
G-244    projected export version of UF-2 Albatross for Norway (see above)
G-273    TFX project
G-279    Apollo proposal
G-283    SOR-/GOR-183 proposal
G-303    series of TFX / VF(A)X Navy Fighter/Attack projects >> F-14 Tomcat
G-305    proposed 4-engined turboprop ASW flying-boat (1961), apparently developed from G-132

Hi Nugo! Thanks for replacing the "no details" of my list with substantial descriptions!

I still have a G-137 that is undocumented. Any idea?

Also, isn't the spelling wrong on G-674? There was a Nutcracker, NOT a Nuttraker! A fuselage folding in flight is wacky enough, but I can't even begin to imagine a radome-carrying aircraft folding in two in flight! LOL

I have the G-273 and the G-310 both as "TFX projects". I figure your source is reliable enough (!) and so G-273 it must be. Besides, the G-310 is posterior to the F-14 Tomcat (G-303) which indicates it was probably a spin-off of the F-111 but not the original program.

Actually, Grumman Aircraft Data From 1930 -- by the Grumman Historical Office, June 1993 which I found at the NHHC files has totally different lists.

Quote
FOREWORD

In 1967 Grant Daly published a compendium of Grumman aircraft statistics entitled Grumman Airplane Data (1930-1967). It contained a wealth of information and was a monumental task -- particularly working without the aid of a computer.

During the past 25 years various attempts have been made to bring the work up-to-date and to correct several errors in the original copy. That it is only now being republished will be some indication of the scope of the task.

The final rework and painstaking wrap-up of the document must be credited to Roger Seybel. Roger spent countless hours, mostly as a volunteer to the Grumman History Center, writing and verifying information with original sources. Without his persistence, you would probably not be reading this today.

Credit must be given to many - but, especially, former Grumman historians Andre Hubbard and Herman "Schoney" Schonenberg for their diligence in saving corrections to the original copy. William Barto and Peter Kirkup, assistant historians, also contributed significantly. Input was also provided by Joseph LeStrange, Joseph Lippert, Lynn McDonald, William Scarborough, Dave Seeman and Salvatore Vitale.

We know that someone will find an error in this copy. If so, please report same to the Grumman History Center at 516-575-2401. The material is now in a word processor; errors can be easily corrected in future editions.

Last.

The reason A-10 and JSTAR are on it is because grumman helped remanufacture some A-10s and was involved in the JSTAR program.

I'm going through boxes of old AvWeek, and I found these pictures. Thought the designation nuts would like it  ;)

I have the complete article, if anyone is interested in learning more about it.
All modern aircraft have four dimensions: span, length, height and politics.   TSR.2 got the first three right - Sir Sydney Camm

One more time - the D-118 was not designated by the Navy as the F12F and Grumman did not refer to the D-118 in their proposals as the F12F*. There is documentation that the Navy intended to designate a production J79-powered F11F derivative as the F12F, drafted a contract for it, and assigned two BuNos to the program. At some point, several years ago, an aviation enthusiast wrongly conflated the F11F upgrade documentation with the unsuccessful Grumman proposal to provide an alternative to the F4H Phantom and assumed that the D-118 was to be the F12F. Along the way the error has also garnered a fanciful popular name, "Lion".

*It was not unknown in the 1950s for a contractor to refer to a proposed aircraft in a brochure and/or presentation by the military designation it would have received. Examples are the "A2F" for an F11F attack derivative and "A3U" for at least a couple of Vought projects. Popular names were also suggested in proposals.

G-1128 (?)   EA-6B Prowler (CME version)
I seem to remember from my days at Grumman that A-6 engineering drawing numbers began with "128" while those specific to the EA-6B began with "1128".  I don't know if it means that the Prowler's model number was indeed G-1128, but it could be a sign.

Similarly, I recall that Gulfstream I drawing numbers began with "159" while those for the Gulfstream II began with "1159".

Not so for G-1159, G-1159A and G-1159B.
But when the G-IV and G-V appeared, some people thought is was logical they were designated G-1159C and G-1159D, and presented this as a fact. Took some time before everybody understood those were 'journalistic inventions' :-(

Apparently G-273 was Grumman's initial proposal for the TFX program in May 1960.

General Dynamics then approached Grumman based on their experience with naval combat programs and together they developed the G-310 which became the F-111B proposal.

G-723: a proposed X-29 variant (X-29B) incorporating the General Electric ADEN (Augumented Deflector Exhaust Nozzle).

The G-723 configuration was tested in NASA's 16-Foot Transonic Tunnel in 1976 (Test 316) and in NASA's 30 X 60 Full Scale Tunnel in 1982-83 (Test 432). More pics of the latter can be found by following the link.

G-636: Grumman proposed HiMAT configuration

Quote
Grumman competed for the NASA highly maneuverable aircraft technology (HiMAT) program around 1973 or 1974. This program was intended to demonstrate the integration of advanced technologies to achieve high sustained transonic maneuver capability. At that time UAVs were called RPVs, and the idea was to build an RPV to demonstrate the technologies. The Air Force was also a sponsor. It was assumed that the technologies would be advanced aerodynamics, aeroelastic tailoring to achieve a passive wing design that would deform to optimum shape at the various g loads, advanced flight controls (relaxed static stability) and thrust vectoring. Grumman originally had a configuration similar to the one being proposed by Rockwell, but Grumman’s evaluation was that with a similar configuration they would lose to Rockwell. In addition, having just put the F-14 into production, there was a strong sense that a variable sweep wing should be proposed. Essentially this was dictated by management: “no proposal goes out the door unless the wing has a pin in it.” So Grumman’s HiMAT proposal used a variable sweep wing with an advanced supercritical airfoil and an aeroelastically tailored wing to obtain its sustained transonic maneuver requirement. The key was to use advanced airfoils and nominally attached flow at the design point. Grumman was not using the vortex flow concepts being exploited by the General Dynamics and Northrop folks with the YF-16 and YF-17. Grumman lost to Rockwell. Note that the YF-16 and YF-17 RFPs came out in January of 1972, so the timing of HiMAT seems a little strange, although nobody knew how those programs were going to develop.

Design #754: « Stalker » variable-geometry VTOL RPV project for AEW role, a 9800 lb aircraft powered by two jet engines: a 9,000 lb thrust lift engine and a 1,300 lb thrust cruise engine.

If built, the 754 was supposed to cruise at 210 knots for 14 hours at altitudes of 27,000 to 37,000 ft. with a 150 lb payload.With a wing span of 51 feet and folding wings, the Stalker would have been able to operate off of a destroyer or a frigate. The Stalker program was halted, presumably because of the two separate engines: when one engine was not in use, the aircraft was carrying dead weight which reduced the available payload.The pictures below are adapted from U.S. Patent #4,726,545 of 1988 (see attachment), and most likely depict the Stalker (not to be mistaken with the eponymous, much more recent Lockheed Martin UAV).

Design #118: Mach 2+ fighter designed as a missile-armed all-weather interceptor to complement the F8U-1. Two ordered in 1955 but cancelled in favour of XF4H-1.

NOTE: This is often found as the "XF12F-1" and even the « Lion », but while the former seems to have never been applied, the latter is most likely the product of some aviation buff's imagination.

Please note with me in this NASA report reference;


Grumman ASM-399-25  FX/VFAX report  (means G-399 FX).
Grumman PDR-636A-2 HiMAT report  (means G-636 HiMAT).
Grumman PDR-623-20 V/STOL Strike Fighter  (means G-623).
Grumman PDR-607A-11 V/STOL Strike Fighter  (means G-607).


Now we can get a conclusion;


PDM-653A-13  the effect of planform taper on supercritical wing design  (may be G-653).
Report 393-73-1  a computer program for calculating the subsonic aerodynamics of complex
                            wing-body configuration (may be G-393).
Report PDR 651AA-5  forward swept wing feasibility study  (sure G-651).
Report 391-69-1  correlation of measure and estimated minimum drag of the F-14A wind
                            tunnel model  (sure G-391,a designation of F-14A).

I already had these in my list, so I guess I found them in the same document as you.

I don't think the G- prefix is automatic. It only applies to aircraft designs (just like the BV- for Boeing or the D for Bell).

What I have for "391" is "Correlation of Measured and Estimated Minimum Drag of the F-14A Wind Tunnel Mode (1969)" so I guess, yes, the number "391" applied to F-14A-related studies. But it doesn't mean "G-391", just 391!!

To confuse matters slightly, during the period that Grumman owned the Flxible Corporation [as Grumman-Flxible] (1978-1983), the somewhat infamous Flxible Metro transit bus was known as the Grumman 870. Also known as the Grumman 870 Advanced Design Bus (it was one of two designs created and accepted for the Urban Mass Transportation Administration's "Transbus" requirement).


CAPTION: New York City Transit Grumman 870 #236, preserved as an historic vehicle

DESCRIPTION: NYC Transit Grumman 870 #236 arrives at Jacob Riis Park on a special excursion as one of eight museum buses in the excursion.

2.2 OVERVIEW OF SYSTEM CONCEPTS

The four SCDs that the GMSA team evaluated were developed by
teams led by Bechtel, Foster-Miller, Grumman, and Magneplane
as examples of potential U.S. systems.  The HSGT alternatives
to which the SCD concepts were compared were the French TGV
steel-wheel-on-rail system and the German TR07 Maglev system.
The Japanese high-speed Maglev system is also described in
this section, but is not included in Table 2.1 due to lack of
performance information.  Table 2.1 summarizes the general
performance results of the GMSA team evaluation.  The section
that follows briefly describes the alternative foreign HSGT
systems and the SCD concepts.
Quote
2-10

2.2.2.3 Grumman SCD





The Grumman concept is an EMS with similarities to the German
TR07.  However, Grumman's vehicles wrap around a Y-shaped
guideway and use a common set of vehicle magnets for
levitation, propulsion, and guidance.  Guideway rails are
ferromagnetic and have LSM windings for propulsion.  The
vehicle magnets are superconducting coils around
horseshoe-shaped iron cores.  The pole faces are attracted to
iron rails on the underside of the guideway.
Nonsuperconducting control coils on each iron-core leg
modulate levitation and guidance forces to maintain a 1.6 inch
(40 mm) air gap.  No secondary suspension is required to maintain
adequate ride quality.  Propulsion is by conventional LSM
embedded in the guideway rail.

Grumman vehicles may be single- or multi-car consists with
tilt capability.  The innovative guideway superstructure
consists of slender Y-shaped guideway sections (one for each
direction) mounted by outriggers every 15-feet to a 90-foot
(4.5 m to a 27 m) spline girder.  The structural spline girder
serves both directions.  Switching is accomplished with a
TR07-style bending guideway beam, shortened by use of a
sliding or rotating section.

and initial work was done by US Army Land Warfare Laboratory,but I asked about the
meaning of DCR-327,is that meaning Grumman G-327,yes or no ?.

The Advanced Design Composite Aircraft (ADCA) study from 1975-1976 includes a reference to a  ASL-D 952-105B supersonic penetration interdiction fighter. Several references to a Grumman ADCA configuration 105B are included in same attached doc link. Im not familiar with Grumman designation system and perhaps more scholarly forum folk might be able to confirm or deny. I'm ASSUMING, and I make this clear - "ASSUMING" a Grumman designation of 925-105B but this doesn't seem right to me. I apologize if this Grumman design has already been mentioned and is not missing from the forum produced list.

see page 72 of this PDF. Other references are made to this ADCA design in the doc below.

My impression (by no means certain) is that these refer to wind tunnels, test "campaigns" and datasets.

As far as is known, Grumman project numbers had not reached 800, even by 1988.
